Patented Aug. 19, 1952 inventien-relate's'toiinp ov me t assume ana'bears partrcti 156 small, test-earn ana-operated diiplica't'oi's us'd inconntioh with stamens.

A prime 'obj ect of my invention is provide improvements in the operation of p t-e'ardsize duplicators to prevefit'the card stock be ngfp'r int ed'frfoins'lipping and getting:sut'tr 'register (inrih'g the printing operati'on.

A further importantobject of'ii1y invention is' to provide dupliator improvement means for faceiiratey locatingt e rocker assembly on the printingbed at the beginning of the printing or inking operation. 1

A further object dfmy invention is to'pr'ovi'de adjustable resilient stop card means for use in connection with card stock of different sizes.

A still further object oi'fny invention is to provide an improvement in the tightening and locking 'rneans for the stencil which is used in confiection with this typ'e'of du ueator.

Afurt'her important object of my'inventlon is to provide a printing bed wherein the body, leg porti' on's and lateral guiderail's arestamped from a single sheet of metaL'sir'nplifyi-ng the production thereof.

Other'Obj sets and advantages embraced in my invention will be disclosed in the renewing deseription and me accompanying illustrations, wherein like partsare referred to by like numerals and in which: Fig. 1 is a perspective view of a stencil-type duplicator of post-card size showing my improvements in connection therewith, and showingcard stock'in printing position on the printing bed assembly with the rocker assembly in position ready for printing.

A capillary ink pad 26, which may be preferably of fabricor cloth, has, rod retaining pockets 21, and 28 7 formed on its two oppositeedges, which, in asso- 'ciatio'n with pad retaining rod 29 and ink piad securing roii '38. maintain the said capillary ink ;pad' '528 stretched tautly over arcuate rocker. surface :22; The said filter retaining rod; 29- is securedinal'igned holes 2-9 in 'earsa25'. .The'filter securing rod 30 is maintained in snappingeene ga'gement by red holding notches .:3 l. in "ears 532,

A roller manipulating knob 39 is centrally located on the top of rocker assembly l0, held by screw 40 together with threaded flange bushing 7 4|, which is fixed in the top of rocker body 2!. A' vented filler cap 42 is mounted over threaded bushing 43 on the top of rocker body 21' and sealed thereagainst by gasket 45: Air venttube fi l connects the top of filler cap 42 with the interior of ink compartment 24.

The filter retaining rod 29 has trunnion like.

extensions 51, to engage the cradle portions IT at the start of the inking procedure, and functions to position the rocker assembly H) in relation to:

printing bed I! and the card stock 19 or 20 as shown in Fig. 1.

' resilient stop means attached to the edge thereof.

It is to be understood that changes may be made in the construction and inthe combination and arrangement of the several parts, provided thatsuch changes fall within the scope of the appended claim.

, Although .I have herein described rather suc- 'cinctly the nature and use of my invention so that persons skilled in the art will have no dif "ficulty apprising themselves of the teachings The said card-stock I B- or 2'0 may be of any size up to the width of the printing bed H and is held in place by the adjustable resilient stop means M. The said printingl card stock is further held in secure registry at the startof the printing operation by the edge of the arcuate rocker'surface 22. This is best illustrated in Figs. 1 and 7. Fig. '7 further illustrates the various positionsof rocker assembly l0 during the card printing procedure, i I

To preparethe rocker assembly for printing, the capillary ink pad 26 is stretched between filter retaining rod 29 and filter securing rod .30 over arcuate rocker surface: 22. The prepared stencil 33 is stretchedover ink pad 26 and locked by stencil tightening and locking rod 31; 'After filling ink'compartment 24 with ink 46 through filler cap 52, the rocker assembly 10 is positioned upon printing bed assembly 9, as shown in Fig. 1, with" rocker locating ears '25 within slotted initial gauge portions 18 and trunnion like extensions 51 resting against cradled portions l1. Adjustable resilient stop means" [4 are adjusted-to fit the card stock either of, the size 19 or 20, as shown in Fig. 1. -'j

The rocker assembly it is rocked over the printing bed 9, as illustratedby various positions in phantomlines in Fig. 7, in which it will be observed that the edge of arcuate rocker surface 22 engages card stock I9 or 29, preventing the slipping thereof which would cause the card to print out of register, It will be observed that the said arcuate rocker surface 22 is in contact with printing bed 9 through-outprinting operation, and is laterally guided by lateral rocker guide'portions l3.

Thecradled portions i7 and slottedkim'tial gaugeportions l8, together with cars 25 and trunnion like extensions 5|, provide a foolproof means of locating rocker assembly H] in the ini-' tial stage of the printingoperation. The card stock designated. 1 9 or'20 may be of post-card size or may be as'small as a calling card or business card. a

Important advantages in connection with my invention reside in the ease with which the stencilis secured, tightened and looked over the arouate printing; surface 22.; by means of the stepped rod seatingrfingers' 38 in connectionwiththe stencil tightening and locking rod 31.".

-A prime advantage in connection with my in:- vention is the ,hereinabove described rocker assembly locating and positioning means which also thereof and, inasmuch as the disclosure is susceptible of various alterations, modifications, and improvements, I hereby reserve the right to all modifications, alterations, and improvements falling within the scope and spirit of my invention', as well as any modifications that are embraced suggestively in the accompanying drawings, and any that may, come within the purview of the foregoing description; my invention to be limited only by the appended claim. 1

Having thus disclosed and revealed my invention, what'I' claim as new and desire to secure by Letters Patentis:

Improved duplicator means comprising, printing bed assembly 'means providedwith a centrally disposed and depressed printing bed portion defining lateral rocker guidemeans, rocker assembly means of a magnitude commensurate with the distance between the said lateral rocker guide means, the said rockerjassembly means being provided with rocker locating ears on one end thereof, slotted initial gauge means provided on thezsaid lateral rocker guide means adapted to locate initially and guide the said rocker locating ears, undercut cradle portions on thesaid lateral rocker guide means; and trunnion-like means on the said rocker assembly means operating on the said undercut cradle portions, the said trunnion-like means in concert with the said undercut cradle portions forming auxiliary locating means to maintain longitudinal location of the said rocker assembly during the rocking period when the said rocker locating earsremerge from the said slotted initial gauge means thus augmenting the locating function of the said rocker locating ears and'the said slotted initial gauge means. p
